SHOWQ(8) System Manager's Manual SHOWQ(8)
showq - list the Postfix mail queue
showq [generic Postfix daemon options]
The showq daemon reports the Postfix mail queue status. It is the pro-
gram that emulates the sendmail `mailq' command.
The showq daemon can also be run in stand-alone mode by the superuser.
This mode of operation is used to emulate the `mailq' command while the
Postfix mail system is down.
The showq daemon can run in a chroot jail at fixed low privilege, and
takes no input from the client. Its service port is accessible to local
untrusted users, so the service can be susceptible to denial of service
None. The showq daemon does not interact with the outside world.
Problems and transactions are logged to syslogd(8).
The showq daemon runs at a fixed low privilege; consequently, it cannot
extract information from queue files in the maildrop directory.
cleanup(8) canonicalize and enqueue mail
pickup(8) local mail pickup service
